BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to hair care compositions. Moreparticularly, the present invention relates to non-foaming orsubstantially non-foaming compositions for cleaning and/or moisturizingthe hair. Still more particularly, the present invention relates tonon-foaming or substantially non-foaming compositions for gentlycleaning and/or conditioning the hair.

[0003] 2. Description of the Related Art

[0004] A large variety of shampoos and conditioners are presently on themarket as hair care products. Traditionally, shampoos have anionicsurfactants as the primary cleaning component. While anionic surfactantsare effective in cleaning, they do not condition the hair. They alsohave a disadvantage in that they are known to be the primary contributorto color fading in dyed hair. Traditional hair conditioning products donot clean the hair or scalp. Consumers who desire a high degree ofcleaning and a high degree of conditioning generally use a separateshampoo and conditioner, which is thus a two step process.

[0005] To provide effective cleaning of the hair with gentle non-foamingproducts, as well as to provide products that effectively clean andcondition the hair in one step, have long presented challenges to thehair care industry. Recently, two-in-one conditioning shampoo productshave been developed. These products allegedly provide both cleaning andconditioning in one step with a single composition. However, suchproducts use anionic surfactants. Consequently, such products are harshon color-treated hair, provide only marginal conditioning benefit to thehair, and foam. Foaming hair care products require greater rinsing timethan products that do not foam.

[0006] In spite of the various personal care products on the market forthe cleaning and/or conditioning of hair, there remains a need fornon-foaming compositions that provide effective and gentle cleaning andconditioning and are easily washed-off.

[0007] There is also a consumer desire for conditioning products that donot impart to the hair a greasy and/or limp feel. A hair compositionthat imparts conditioning while leaving the hair feeling clean to thetouch is particularly desired by consumers. Clearly, consumers desire,and would benefit from, a conditioning product that may be used alonebetween shampoos to condition without leaving a feeling of chemicalresidue on the hair, i.e., “build-up”.

[0008] The present invention conditions hair as effectively as aconditioner, while cleaning the hair as effectively as a shampoo. Thepresent invention also provides a single composition or product thatprovides cleaning and conditioning and does not foam. Thus, the presentinvention provides a desired time saving benefit.

SUMMARY OF THE INVENTION

[0009] It is an object of the present invention to provide compositionsthat effectively clean the hair, and are non-foaming or at leastsubstantially non-foaming.

[0010] It is another object of the present invention to providecompositions that effectively clean and condition the hair withoutleaving the hair limp or feeling greasy (or having build-up).

[0011] It is still another object of the present invention to providecleaning compositions for the hair that are gentle to color-treated ordyed hair.

[0012] It is yet another object of the present invention to provide suchnon-foaming or substantially non-foaming compositions that are easilyrinsed off the hair and are more environmentally friendly than foamcompositions.

[0013] It is a further object of the present invention to provide amethod for cleaning and/or conditioning the hair using compositions ofthe present invention.

[0014] These and other objects and advantages of the present invention,and equivalents thereof, are achieved by hair cleaning compositions,hair cleaning and conditioning compositions, compositions that protectcolor-treated hair, and methods of applying such compositions inaccordance with the present invention. The hair cleaning compositions ofthe present invention have at least one non-ionic surfactant in aneffective amount to clean hair. The present compositions can optionallyhave other surfactants. The amount of the non-ionic surfactant isgreater than the amount of the other surfactant. The presentcompositions can also have a hair conditioning ingredient.

[0015] Preferably, the present compositions are free or substantiallyfree of anionic surfactant. Should the present compositions have one ormore anionic surfactants, the present composition must have at least onenon-ionic surfactant(s) present in an amount greater than the totalamount of anionic surfactants.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The compositions of the present invention have one or more activeingredients or blends of active ingredients that effectively cleanand/or condition the hair in one step. The present compositions provideeffective cleaning and conditioning to the hair and are notably gentleto color-treated hair. In addition, the compositions of the presentinvention may also be used to condition the hair between shampoos, withless build-up than prior art conditioning compositions. Further, theremoval of build-up allows styling products to hold better.

[0018] To “effectively clean the hair” means to remove at least 20%sebum and/or residue from the hair. Effectively clean means topreferably remove at least 50% sebum and/or residue, and more preferablyremove at least 90% of sebum and/or residue, from the hair. To“effectively condition the hair” means to provide smoothing of the haircuticle. Smoothing of the hair cuticle also serves to decrease“tangling”, which means proximate strands of hair becoming entwined.

[0019] The present invention also provides compositions that areentirely or substantially non-foaming. “Substantially non-foaming” meansthat compositions have little or no lather, suds, or foam when workedinto the hair. The present compositions provide superior conditioningbenefits in contrast to all known foaming or foam compositions. Thepresent compositions are gentle, mild, and can also be rinsed from thehair faster than foaming compositions, thus providing a time-savingadvantage.

[0020] The present compositions have one or more non-ionic surfactants.When used on the hair, the non-ionic surfactant cleans sebum and/orproduct residue. This cleaning benefit is provided substantially withoutfoaming.

[0021] The non-ionic surfactant of the present invention includes, butis not limited to, at least one of the following: polysorbate 60(Crillet 3), ppg-5-ceteth-20 (the polyoxypropylene, polyoxyethyleneether of cetyl alcohol), peg-20 sorbitan isosterate (Crillet 6),polysorbate 80 (Crillet 4), alkoxylated alcohols, alkoxylated polyolesters, or any combinations thereof. Especially preferred non-ionicsurfactants are polysorbate 60 and ppg-5-ceteth-20.

[0022] The compositions of the present invention have at least onenon-ionic surfactant in an amount effective to clean hair. The totalhair cleaning effective amount of the one or more non-ionic surfactantsin the present compositions is about 0.5 wt % to about 30 wt % based onthe total weight of the composition. Preferably, the total amount of thenon-ionic surfactant(s) is about 1 wt % to about 20 wt %, and morepreferably about 3 wt % to about 12 wt %, based on the total weight ofthe composition.

[0023] The compositions of the present invention (especially whenprimarily a cleansing composition) can optionally have one or more otheror optional surfactants. These optional surfactants can be any knownsurfactants. However, the total amount of the one or more non-ionicsurfactants is greater than the total amount of all optionalsurfactants.

[0024] Preferably, the compositions of the present invention are free orsubstantially free of anionic surfactants. The term “substantially free”means that an anionic surfactant, if present, is in an amount less than5 wt % based on the total weight of the composition. Thus, it ispreferred that the optional surfactants are not anionic surfactants.

[0025] In the present compositions that have one or more anionicsurfactants, the total amount of non-ionic surfactant on a weight basisis greater than the amount of the total amount of anionic surfactant. Ona weight basis, the ratio of non-ionic surfactant(s) to anionicsurfactant(s) is greater than about 1.5:1, preferably greater than about5:1, more preferably greater than about 10:1, and optimally greater thanabout 100:1. Unlike the prior art that uses anionic surfactants ascleaning agents, the present compositions use one or more non-ionicsurfactants as the primary cleaning ingredient.

[0026] In combination with the one or more non-ionic surfactants, thepresent compositions may conveniently employ any known activeconditioning ingredient. The preferred active conditioning agent is alsoan optional or other surfactant. The most preferred optionalsurfactant/active conditioning agent is one or more cationicsurfactants. A preferred cationic surfactant ispalmitamidopropyltrimonium chloride.

[0027] Other active conditioning ingredients that can be used in thecompositions of the present invention include, but are not limited to,one or more of the following: fatty alcohols (e.g., cetearyl alcohol),cationic polymers, conditioning polymers, cetyl esters, silicones orsilicone compounds, silicone polymers, or any combinations thereof.

[0028] The silicone or silicone compounds useful as an activeconditioning agent in the present compositions include, but are notlimited to, one or more dimethicones, which are a mixture of fullymethylated linear siloxane polymers end blocked with trimethysiloxymoieties.

[0029] In compositions of the present invention that have one or moreactive conditioning ingredients, the total amount of non-ionicsurfactant(s) is preferably greater than the total amount of all activeconditioning ingredient(s). The total amount of the active conditioningingredients in the present compositions is a hair conditioning effectiveamount. A hair conditioning effective amount is preferably about 0.1 wt% to about 20 wt %, more preferably about 0.5 wt % to about 15 wt %, andmost preferably about 2 wt % to about 10 wt %, based on the total weightof the composition.

[0030] On a weight basis, the ratio of non-ionic surfactant(s) toconditioning ingredient(s) is about 5:1 to about 6:5. Preferably, theratio of non-ionic surfactant(s) to conditioning ingredient(s) is about2:1 to about 4:3, and more preferably about 3:2.

[0031] The compositions of the present invention are topicalcompositions. Such topical compositions are preferably in the productform of a cream, but can be formulated in any suitable product form.Such other suitable product forms include, but are not limited to, adispersion, an emulsion, a foundation, a gel, a liquid or a lotion.Preferably, the present compositions can be in the form of a homogeneousphase formulation or an emulsion. The emulsion form includes, but is notlimited to, oil-in-water, water-in-oil, or multiple including triple,phase emulsions. These emulsions can cover a broad range ofconsistencies including thin lotions (which can also be suitable forspray or aerosol delivery), creamy lotions, light creams and heavycreams.

[0032] The present compositions preferably include a vehicle. A usefulvehicle is one that is acceptable for topical applications. Usefulvehicles include, but are not limited to, one or more aqueous systems,glycerins, C₁₋₄ alcohols, fatty alcohols, fatty ethers, fatty esters,polyols, glycols, water, or any combinations thereof.

[0033] Optionally, the present topical composition may include one ormore adjuvants or adjuvant ingredients. Such adjuvants include, but arenot limited to, one or more amphoteric surfactants (which can also be anoptional surfactant), antioxidants, anti-dandruff agents, botanicalextracts or ingredients, chelating agents, cooling agents (e.g.,menthol), colorants, dyes, emollients, emulsifiers, fragrances,lubricants, moisturizers, pH adjusting agents, preservatives, proteins,protein hydrolysates or other protein derivatives, silicones,stabilizers, thickeners, viscosity modifiers, vitamins, UV agents, orany combinations thereof.

[0034] Such adjuvants are used in an amount up to about 20 wt % based onthe total weight of the composition. Preferably, the adjuvants arepresent in an amount about 1 wt % to about 15 wt %, and more preferablyabout 5 wt % to about 10 wt %, based on the total weight of thecomposition.

[0035] The pH of the compositions of the present invention is about 3 toabout 8.5. Preferably, the pH is about 4 to 7.5, and more preferablyfrom about 4.5 to 7. The pH may conveniently be adjusted using pHadjusting agents such as citric acid, succinic acid, sodium hydroxide,triethanolamine, or any combinations thereof.

[0036] The compositions of the present invention can conveniently beused in effective amounts to clean the hair, to clean and condition thehair, and to protect color-treated hair in one step.

[0037] The present compositions may also be used between shampoos as amethod of effectively conditioning the hair, with less build-up thanconventional conditioning compositions. People with dry or damaged hairtend to overuse conditioning products because of a perceived need forthem. However, when used together with styling products, theconditioners plasticize the styling products and make style retentionless effective. Moreover, the conditioners also typically create residuebuild-up on the hair, which similarly affects the holding ability of thestyling products, especially under high humidity. The removal ofbuild-up allows styling products to hold better. The compositions of thepresent invention are gentle and mild enough to overcome theplasticization and build-up issues of the prior art, while providingeffective conditioning. Preferably, a conditioning method of the presentinvention would include the steps of: applying the composition to andthrough the hair; leaving the composition on the hair for, preferably,greater than two minutes; and rinsing the hair.

[0038] The foregoing conditioning method may be augmented by adding oneor more of the following steps:

[0039] (1) leaving the composition on the hair for greater than threeminutes; or

[0040] (2) applying heat, preferably by a warm towel, to the hair whilethe composition is on the hair.

[0041] Most preferably, the composition is left on the hair for aboutthree to five minutes. Also most preferably, the heat is applied bywrapping the hair with a heated towel, which is preferably a moistenedheated towel. Shampooing the hair beforehand is not necessary as thehair will be cleansed as it is conditioned. Simply rinsing the hairafterwards with water will suffice. Alternatively, the consumer maypractice this method after or prior to shampooing. The conditioningmethod provided by the present invention is particularly useful forthose consumers who have damaged hair, either from coloring, perming orother harsh treatments. The addition of cooling agents, such as menthol,is particularly pleasing/soothing to consumers when combined with thestep of applying heat to the hair.

[0042] The following is an example of a preferred composition accordingto the present invention. Unless indicated otherwise, all amounts are inpercentage by weight, based on the total weight of the composition.

EXAMPLE

[0043] INGREDIENT WT % Non-Ionic Surfactant (e.g., 3 to 12polyoxyethylene (20M) sorbitan monostearate, PPG-5-Celeth-20)Conditioning Agents (e.g., silicones such 2 to 10 as dimethicone and/ordimethiconol, cationic polymers, such as guar HPT chloride, or cationicsurfactants, such as palmitamidopropyltrimonium chloride, and/or fattyalcohols, such as cetyl alcohol or stearyl alcohol) Adjuvants (e.g.,menthol, sodium 0.5 to 5 hyaluronate) Preservatives (e.g.,methylparaben, 0.2 to 1 propylparaben) Water Qs to 100

[0044] A composition within the scope of the present invention as setforth above was compared against commercially available Pantene Smooth &Sleek Shampoo and Conditioner products. A bleached hair swatch wasshampooed, conditioned and rinsed six consecutive times with the Panteneproducts. The swatch was then treated with a commercial mousse, andwrapped around a roller. The swatches were placed in an oven at 120 Ffor two hours for even distribution of heat. They were then removed andallowed to equilibrate at room temperature for thirty minutes. Theroller was then removed to reveal a curled swatch. On a separatebleached swatch, the same regimen was followed, except, on the third andsixth time, the Pantene Conditioner was replaced with the conditioningcomposition of the present invention.

[0045] Both swatches were then measured using an industry Delta anglemethod. The Delta angle method measures the amount of curl retentionloss over time. The lower the better. FIG. 1 shows the Delta angleincrease measured over time as related to the comparison test proceduresset forth above. As the data in FIG. 1 illustrates, the use of thecomposition of the present invention provides enhanced style holdability, even up to four (4) hours.

[0046] It should be understood that the foregoing description is onlyillustrative of the present invention.
